In this song I think Kris Roe is talking about how much being on the road changes you. In this case, he was so excited to get to be going home to his girlfriend, and things aren't like he expected, they are akward and uncomfortable, and he realizes that he doesn't love her anymore. He realizes that their chance has passed. And though he might be upset, he's kinda happy that it happened.
